Switchable clutch for a steer-by-wire steering system, steer-by-wire steering system, steering gear, steering input device and method for operating a steer-by-wire steering system and vehicle

摘要

The invention relates to a switchable, interlocking coupling for a steer-by-wire steering system with a mechanical fallback level for a vehicle, a steer-by-wire steering system, a method for its operation and a vehicle, the coupling having a first coupling part, which can be coupled non-rotatably to a driver-side steering shaft, a second coupling part which can be coupled non-rotatably to a wheel-side steering shaft, and an actuator device, the two coupling parts being engageable and disengaging with one another by means of the actuator device, and when the clutch is disengaged is, the first coupling part is freely rotatable with respect to the second coupling part and the two coupling parts each have an end face with several elevations and depressions that can slide against each other, so that when the coupling is closed in the event of a rotational angle offset, a relative rotation between the first coupling part and the second Clutch is partially effected, which leads to a compensation of at least a part of the rotation angle offset.
